President Donald Trump observed the 16th anniversary of the 9/11 terror attacks Monday, his first presidential remembrance of the attack that killed nearly 3,000 Americans.

The president, joined by the first lady, called the occasion “extraordinary.”

“Our values will endure. Our people will thrive,” Trump said, speaking at the Pentagon in tribute to those who perished there on 9/11. “Our nation will prevail and the memory of our loved ones will never, ever die.”

“The terrorists who attacked us thought they could incite fear and weaken our spirit, but America cannot be intimidated,” Trump said. “And those who try will soon join the long list of vanquished enemies who dared to test our mettle.” (Read more from “Trump Commemorates 9/11 Anniversary” HERE)
